Specification of Letters Patent.

Patented Apr. 24, 1917.

Original application-filed. December 30, 1915, Serial No. 69,469. Divided and this application filed June 10, 1916. Serial No. 102,856.

To all whom itmay concern:

Be it known that I, ADAM B. MEINHARDT, residing at Paxico, in the county of VVabaunsee and State of Kansas, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

My invention relates to certain new and useful improvements in harvesters and the present invention especially has for its object to provide improvements in the construction of the grain head straps and allied parts of the grain platform, and the present invention particularly has for its object to provide such improved construction as will be especially adapted for use in connection with the harvester which forms the subject-matter of my application for patent filed December 30, 1915, Serial No. 69,469 of which the present application is a divisional part.

The present invention has for its special object to provide an improved regulator or adjustment for the grain head straps whereby they can be readily and conveniently manipulated by the operator during the running of the machine, for long or short grain, the operator being thereby enabled to adjust the straps while the harvester is in full operation and thus do away with the necessity of stopping the machine in order to effect the adjustments when desired.

The invention also provides means in connection with the platform canvas, whereby the butt ends of the, grain, as well as the head ends, are carried evenly onward to the elevating canvas, a thing that is of considerable benefit, and is not obtainable by any of the harvesters now in common use, with which I am at present familiar.

The invention also resides in those novel features of construction, combination and arrangement of parts, all of which will be first fully described, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a top plan view of a portion of a harvester, parts being removed and other parts broken away, showing the invention applied.

Fig. 2 is a side elevation of the same, parts being removed in the interest of clearness.

Fig. 3 is a detail elevation, parts being broken away, of the grain head strap regulator.

Fig. 1 s top plan view of the parts shown in 1* 1g. 3.

Referring now to the accompanying drawings, in which like numerals and letters of reference 1nd1cate like parts in all of the figures 257 is the platform canvas or conveyor which, in its general nature, (eX- cept as later explained) is of the usual construction, being driven through a shaft 258 and sprocket 259 from the main driving chain 195. The canvas has the usual slats 260 and in order to effect a more even conveying of the grain stalks to the elevator, I provide one or more oval knobs 261 on the canvas between the slats (see Figs. 1 and 2).

262 designates the grain head straps (see Fig. 1) of which one or more may be used, and in order to adjust the said straps for different height grain, while the machine is in operation in the field, I have invented a mechanism which is best shown in Fig. 2, by reference to which it will be noted that I provide, on the outer side of the platform 257, and in close proximity to the canvas, a pipe or tube 263, the front end of which is sustained by a bracket 26d and the rear end by a bracket 266 over which and over guide sheaves 267 on the body frame, the adjusting cable 268 passes. The pipe 263 is longitudinally slotted as at 269 to permit passage of the screw270 that fastens the slide bar 271 to the shiftable plug 272 that operates in the pipe and to which the cable 268 is fastened at 273. The plug 272 is pushed forward by a coil spring 274 within the pipe, against the tension of which the cable 268 acts.

Theslide bar 271 is also supported by a collar 275 which slides on the pipe 263 (see Figs. 3 and a) and it has one or more cars 276 into which the grain head straps 262 are hooked as at 277. n

The cable 268 runs to the operating mechanism whichis located on the operators platform 207 X at the rea'r'thereof near the operators seat 470 so as to be conveniently within his reach. This operating mechanism comprises a grooved wheel 27 8 on which the cable 268 may be wound to move the grain head straps rearwardly. The wheel 278 is mounted with its spindle 279 in bearings in a standard 280 and it has a back check ratchet 281 with which the holding pawl 282 engages (see Fig. 2). The cable is Wound up by turning the wheel 278 by a crank 283 and the pawl 282 is lifted to release. the wheel by means of a treadle 28.4; having a rod 286 that engages the pawl, the treadle being pivoted at 285 (see Fig. and a spring 287 being provided, if desired, to raise the treadle and maintain the normal engagement between the pawl 282 and the ratchet 281.

In practice, as the grain is cut and falls upon the platform the head portions of the grain travel faster than the butts or cut off end of the grain, the cut off end of the grain being held back by the grain which is being cut by the sickle or knife, thus giving the heads a chance to run faster than the cut off end of the grain, consequently the grain heads go up the elevating conveyer too rapidly, under ordinary conditions, which should not be, as it makes a ragged bundle or sheath. By providing the grain head straps 262 they may be drawn, over to the farther end of the platform (toward the left in Fig. 1) as desired to retard the feed of the grain heads, while the knobs 261 engage the butts of the cut grain and thus tend to more positively feed the grain butts toward the elevating conveyer. By adjusting the position of the straps 62 along the canvas a uniformly even parallel feeding of the cut grain to the elevating conveyers 808 may be had. It should be adjusted to accord with the grain being cut, whether it be long grain or short grain and the adjustment may be made at the will of the driver while the machine is running over the ground and in operation.

From the foregoing description takenin connection with the accompanying drawing, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art.
